Question

Give two chemical tests to distinguish propan-$2$-ol and $2$-methylpropan-$2$-ol.

Answer 1

(i) When propan-$2$-ol and $2$-methyl-propan-$2$-ol are treated with copper at $573$k, different products are formed. From the nature of the products we can distinguish them.
(ii) Lucas test. When propan-$2$-ol and $2$-methyl-propan-$2$-ol are treated with lucas reagent(conc. $HCl+$ anhydrous $ZnC{l}_2$) at room temperature, from the turbidity formation, we can distinguish them.
